Synthesis of post-metallocene catalyst and study of its olefin polymerization activity at room temperature in aqueous solution followed by prediction of yield

摘要

In the research work presented here, the following work has been carried out: (1) Synthesis of the post-metallocene complex (2) Investigation of its olefin polymerization activity at room temperature in aqueous solution (3) Characterizations to verify the synthesized catalyst (4) Calculation of the yield of the synthesized polymer by varying the moles/amount of catalyst, co-catalyst, and monomer (5) Prediction of an appropriate proportion of catalyst, co-catalyst, and monomer, which can result in maximum yield. The polymer sample has also been characterized by different instrumental techniques viz. H-1 NMR spectroscopy and dynamic light scattering (DLS) to investigate the properties of the polymer. Moreover, for identifying the best combination of complexes, response surface methodology has been adopted. From the analyses, a safe zone has been predicted, which can result in optimum yield. The obtained zone has been validated by performing more experiments. From the results, it has been perceived that the developed methodology has the capability to predict the suitable amount of complexes to be taken so that the yield is maximum.
